    nullcounts of all fields

    Paulo Hersan

      Hi all,


      I was wondering if there was an easy way to leverage the system field, $Field, in order to set up a table that lists the field name and its nullcount


      I want the output to be something like:

      FieldName          NullCount

      ID                        0

      Age                    10

      Region                 3

      Name                   2

      Address              47

      Email                  40

      SSN               28437



      I can write script and loop through all the field names and get the nullcounts that way, but I would like to keep the association on the calculation as well. For example, if I pick USA as the region, obviously the NullCount for Region would go down to 0, but I would be able to see the nullcounts of all other fields where Region is USA. Is there a way to do this, without brute force?


      Thanks in advance,

          This seems to work with $Field as the dimension.  You have to list each table you care about separately since you have a different ID to count for each table.  I suspect in your case all the fields you care about are on a single table so you can simplify that part.  There's probably a simpler way than this.


          $(=concat(',count({<['&$Field&']-={}>} ID)')))
          $(=concat(',count({<['&$Field&']-={}>} ID2)'))))


          Edit: OK, here's a little simpler.  I still think it should be easier than this.
